  • the upper tool of the tool comprises an upper displacement unit, the upper displacement unit comprising an upper base for connection to a press ram of a press unit and an upper die support, the upper dies being arranged on the upper die support and the upper die support Die support is guided movably in the horizontal direction on the upper base and that the lower tool of the tool comprises a lower displacement unit, the lower displacement unit comprising a lower base for connection to a press table of the press unit and a lower die support, the lower dies on the lower die support are arranged and wherein the lower die support is guided on the base movable in the horizontal direction.
  • Such a tool can be operated in a press unit without the latter having to be converted for this purpose.
  • the upper die support is guided on the upper base so that it can be linearly displaced in the horizontal direction and that the lower die support is guided on the lower base such that it can be linearly displaced in the horizontal direction.
  • Such a mechanism can be implemented in a structurally simple and inexpensive manner.
  • the upper displacement unit comprises an upper drive, wherein the upper die support is movable relative to the upper base by means of the upper drive and that the lower displacement unit comprises a lower drive, the lower die support relative to the lower drive the lower base is movable. This makes it easy to automate the operation of the tool.
  • the press comprises a pressing device and a tool, the pressing device comprising a press frame, a press ram and a press table, wherein a press stroke can be executed with the press ram when the press unit is actuated, the tool comprising an upper tool and a lower tool, the upper tool with the press ram, the lower tool being connected to the press table, the tool being designed as a multi-stage tool, the upper tool comprising n dies, the lower tool comprising n dies, the upper tool of the tool comprising an upper displacement unit, the upper Sliding unit comprises an upper base for connection to the press ram of a press unit and an upper die support, the upper dies being arranged on the upper die support and the upper die support on the upper base in the horizontal direction is movably guided and wherein the lower tool of the tool comprises a lower displacement unit, wherein the lower displacement unit comprises a lower base for connection to the press table of the press unit and a lower die support, the lower dies are arranged on the lower die support and the lower die
  • the tool of the press is designed according to at least one of claims 1, 3 or 4. This results in the advantages mentioned for the respective claims.
  • the upper die support can be moved along an upper travel axis of the upper drive and the lower die support can be moved along a lower travel axis of the lower drive, that the travel axes run parallel and that these travel axes run at right angles to a vertical axis y on which the press ram moves during a press stroke. This enables a central loading of the press ram with each forming step.
  • the press is designed as a screw press. This allows the individual die pairs with Forming forces individually adapted to the respective die pair can be used.
  • a tool 1 according to the invention is shown in a schematic side view.
  • the tool 1 comprises an upper tool 30 and a lower tool 60.
  • the tool 1 is designed as a multi-stage tool.
  • the upper tool 30 comprises two dies A and b.
  • the lower tool 60 comprises two dies a, b.
  • the dies A, B of the upper tool 30 and the dies a, b of the lower tool 60 are in relation to one another can be positioned horizontally in at least two positions I and II.
  • the upper tool 30 and the lower tool 60 or the tool 1 are shown in the first position I.
  • the upper tool 30 is pushed to the right in the direction of arrow x and the lower tool 60 is pushed to the left in the direction of arrow x 'such that the first die A of the upper tool 30 and the last, second die b of the lower tool 60 together Form die pair Ab.
  • a first forming process can be carried out on a workpiece W with the pair of dies Ab in the first position I of the tool 1.
  • a respective pressing device 101 is shown in a schematic side view.
  • the pressing device 101 comprises a press frame 102, a press ram 103 and a press table 104.
  • the tool 1 is arranged between the press ram 103 and the press table 104.
  • the press ram 103 is arranged on the press frame 102 so that it can be moved vertically, optionally in the y-direction and y'-direction, so that a press stroke can be executed with the press ram 103 when the press device 101 is actuated.
  • a press P according to the invention is formed by the pressing device 101 and the tool 1 built into it.
  • the press ram 103 is in a raised position P103-1 and in the Figures 2 and 4th shown in a depressed position P103-2.
  • the tool 1 is built into the press unit 101, the upper tool 30 being connected to the press ram 103 and being able to move vertically in the y-direction or the y'-direction with the latter, and the lower tool 60 being connected to the press table 104.
  • the upper tool 30 of the tool 1 comprises an upper displacement unit 31 and the lower tool 60 of the tool 1 includes a lower displacement unit 61.

  • the upper displacement unit 31 comprises an upper drive 34 by means of which the upper die carrier 33 is relative to the upper base 32 and thus also relative to the press ram 103 of the Position I can be moved into position II and vice versa.
  • the lower displacement unit 61 comprises a lower drive 64 by means of which the lower die carrier 63 relative to the lower base 62 and thus also relative to the press table 104 of the Position I can be moved into position II and vice versa.
  • the travel axes x34 and x64 run parallel to one another and are at right angles to a vertical axis H103, on which the press ram 103 moves during a press stroke.
  • the press P is designed as a screw press SP.
  • dies B and a of the second pair of dies Ba are accessible for die lubrication from below and from above in the first position I of the tool 1 despite a closed first die pair Ab.
  • Die lubrication is carried out by a first spray head 105, which sprays the upper die B of the second pair of dies Ba, and by a second spray head 106, which sprays the lower die a of the second pair of dies Ba.
